Asp. NET how to prevent multiple click submit button Repeat Submit

Today to make a system, because the server is a bit slow, so it is often clicked two or three times, the data submitted is multiple times. So to make the button click, you can't click again.

For a button, to make the restore color, as long as the this.disabled=true on it, but in. NET, the message cannot be submitted after the onclick is added. So add the following code.

<asp:button id= "btnsub" runat= "Server" text= "Reply" onclick= "Btnsub_click"/>

BTNSUB.ATTRIBUTES.ADD ("onclick", "this.value=" is being submitted, please wait a moment ... "; this.disabled=true;" + this. GetPostBackEventReference (btnsub) + ";");

After that, it'll be all right.
